Answer 1

Due to breaking changes in Lombok version 1.16.20 you need to set the following property in your lombok.config file (if you don't have this file you can create it in your project root):

lombok.anyConstructor.addConstructorProperties=true

This is described in the Lombok changelog: https://projectlombok.org/changelog.

After that the @Value should be accepted again by Jackson.
